Software

Calibrating the NI 9211

 

requires the installation of NI-DAQmx 9.2 or later

 

on the calibration 

system. You can download NI-DAQmx from 

ni.com/downloads

. NI-DAQmx supports 

LabVIEW, LabWindows

/CVI

, C++, and .NET. When you install NI-DAQmx, you only need 

to install support for the application software that you intend to use.
